Answer: 6751 L

Explanation:

1000 mL = 1 L

so dividing 6751 by 1000 gives .6751 L

Answer:

A-L

Explanation:

Since before the change, the substance is described as having atoms "close together" and "cannot slide past one another", one can assume this is a solid, since in both liquids and gases, the atoms can move around more or less freely.

Then, it explains that the new substance "can fill a container", which is a property of both a liquid and a gas.

Thus, the answer would be either P, solid to liquid, or L, solid to gas.

Since P is not an option you can choose, by process of elimination, that leaves L, or option A.

Answer:

A chemical property is a characteristic of a substance abserved in chemical reactions.

Explanation:

Some major chemical properties include flammability, toxicity, heat of combustion, pH value, rate of radioactive decay, and chemical stability.

Answer:

Protons

Protons are another type of subatomic particle found in atoms. They have a positive charge so they are attracted to negative objects and repelled from positive objects.

Answer:

1.88 x 10^5

Explanation:

You have to round because all of the numbers in 187515.4207 are significant

Round to: 188000

Put in scientific notation:

1.88 x 10^5

Answer:

well scientific notation would be = 1.875154207 × 10^5

you cant rlly simply the number any further to get 3 sig figs

youd need something like 187 to be 3 sig figs

are you saying the question correctly?

Answer:

The answer options provided are incorrect. The correct answer is 0.009g

Explanation:

Using PV = nRT

Where;

P = pressure (atm)

V = volume (L)

R = gas constant (0.0821 Latm/Kmol)

T = temperature (K)

n = number of moles

Based in the information provided;

V = 107mL = 107/1000 = 0.107L

P = 104.8kPa = 104800 Pa = 1.03atm

T = 30°C + 273.15 = 303.15K

PV = nRT

1.03 × 0.107 = n × 0.0821 × 303.15

0.1102 = 24.89n

n = 0.1102/24.89

n = 0.0044 mol

mole = mass/molar mass

Molar mass of H2 = 2g/mol

mass = molar mass × mole

mass = 2 × 0.0044

mass = 0.0088

mass = 0.009g

Answer:

Explanation: A.0

Answer:

Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.

The He or helium is a smallest element and the Fr or the francium is largest.

The atomic radius is a chemical element and is a measure of the atomic size. It typical distance from the center of the nucleus is bounded by the electron shells.  

The atomic radii can vary on basis of the periodic table. Hence can be seen as the radius increases from top to the bottom in a group, and then decreases from left to the right across a period.

Radio Waves have the lowest frequency but the highest

Explanation:

From the acronym GUX = VIR

Wavelength, deviation, and refractive index increases to the right

but frquency increases to the left

Answer:

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we are finding the new pressure

[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]

From the question we have

[tex]P_2 = \frac{2 \times 760}{1.8} = \frac{1520}{1.8} \\ = 844.4444...[/tex]

Answer: B

Explanation: USA test prep, K12

Answer:

Atomic number is the number of protons in an isotope or element.

Explanation: The atomic number is the same number of protons in an element or isotope and if said isotope is neutral than it is the same number of electrons.

Example: Atomic number = 19 Protons = 19 if neutral Electrons = 19

Answer:

Nickel

Explanation:

Answer:

1 g

Explanation:

Given data:

Volume of solution = 250 mL (250 mL × 1 L/1000 mL = 0.25 L)

Molarity of solution = 0.1 M

Amount of sodium hydroxide = ?

Solution:

Molarity = number of moles / volume in L

0.1 M = number of moles /0.25 L

Number of moles = 0.1 M × 0.25 L

            M = mol/ L

Number of moles = 0.025 mol

Mass of sodium hydroxide:

Mass = number of moles × molar mass

Mass = 0.025 mol ×40 g/mol

Mass = 1 g

Answer:

There are 13 numbers in an aluminum atom and 13 electrons.

Answer:

Approximately [tex]64\%[/tex].

Explanation:

[tex]\displaystyle \text{Percentage Yield} = \frac{\text{Actual Yield}}{\text{Theoretical Yield}} \times 100\%[/tex]

The actual yield of [tex]\rm O_2[/tex] was given. The theoretical yield needs to be calculated from the quantity of the reactant.

Balance the equation for the hydrolysis of water:

[tex]\rm 2\, H_2O \, (l) \to 2\, H_2\, (g) + O_2\, (g)[/tex].

Note the ratio between the coefficient of [tex]\rm H_2O\, (g)[/tex] and [tex]\rm O_2\, (g)[/tex]:

[tex]\displaystyle \frac{n(\mathrm{O_2\, (g)})}{n(\mathrm{H_2O\, (aq)})} = \frac{1}{2}[/tex].

This ratio will be useful for finding the theoretical yield of [tex]\rm O_2\, (g)[/tex].

Look up the relative atomic mass of hydrogen and oxygen on a modern periodic table.

Calculate the formula mass of [tex]\rm H_2O[/tex] and [tex]\rm O_2[/tex]:

[tex]M(\mathrm{H_2O}) =2\times 1.008 + 15.999 = 18.015\; \rm g \cdot mol^{-1}[/tex].

[tex]M(\mathrm{O_2}) =2\times 15.999 = 31.998\; \rm g \cdot mol^{-1}[/tex].

Calculate the number of moles of molecules in [tex]9.8\; \rm g[/tex] of [tex]\rm H_2O[/tex]:

[tex]\displaystyle n(\mathrm{H_2O}) = \frac{m(\mathrm{H_2O})}{M(\mathrm{H_2O})} = \frac{9.8\; \rm g}{18.015\; \rm g \cdot mol^{-1}} \approx 0.543991\;\rm g \cdot mol^{-1}[/tex].

Make use of the ratio [tex]\displaystyle \frac{n(\mathrm{O_2\, (g)})}{n(\mathrm{H_2O\, (aq)})} = \frac{1}{2}[/tex] to find the theoretical yield of [tex]\rm O_2[/tex] (in terms of number of moles of molecules.)

[tex]\begin{aligned} n(\mathrm{O_2}) &= \displaystyle \frac{n(\mathrm{O_2\, (g)})}{n(\mathrm{H_2O\, (aq)})} \cdot n(\mathrm{H_2O}) \\ &\approx \frac{1}{2} \times 0.543991\; \rm mol \approx 0.271996\; \rm mol \end{aligned}[/tex].

Calculate the mass of that approximately [tex]0.271996\; \rm mol[/tex] of [tex]\rm O_2[/tex] (theoretical yield.)

[tex]\begin{aligned}m(\mathrm{O_2}) &= n(\mathrm{O_2}) \cdot M(\mathrm{O_2}) \\ &\approx 0.271996\; \rm mol \times 31.998\; \rm g \cdot mol^{-1} \approx 8.70331 \; \rm g \end{aligned}[/tex].

That would correspond to the theoretical yield of [tex]\rm O_2[/tex] (in term of the mass of the product.)

Given that the actual yield is [tex]5.6\; \rm g[/tex], calculate the percentage yield:

[tex]\begin{aligned}\text{Percentage Yield} &= \frac{\text{Actual Yield}}{\text{Theoretical Yield}} \times 100\% \\ &\approx \frac{5.6\; \rm g}{8.70331\; \rm g} \times 100\% \approx 64\%\end{aligned}[/tex].
